SHIPS SIGNAL.

lSPECIIEICATION forming part of Letters Patent No. 240,504, dated April 26, 1.881.

Application filed July 19. 1880.

Toall 'whom it may concern:

Be it known that we, SAMUEL S. CAMPBELL and JOSEPH H. EASTMAN, ot' Boston, in the county of Suffolk and State of Massachusetts,

1 by sounds repeated at certainintervals, accordtwo notes would indicate anortheastdirection one note, a pause, and three notes would indicate north, northeast, and so on through the several points of compass. v

Our invention consists in an improved construction ofthe toothed cylinder and the operative mechanism whereby the space occupied by t-he apparatus is very much reduced, and the instrument rendered more certain in action and less liable to get out of order than the apparatus described in the abovemamed patent. Y

Referring to the drawings, Figure l represents a sideelevat-ion of an apparatus embodying our improvements. Fig. 2 is a partial sectional view, enlarged, of Fig. lon the line m Fig. 3 is a view of the bell hammer and arm, shown enlarged. Fig. 4 shows a lantern for signaling by a flash light.

Arepresen ts the cylinder, which is composed of a series of annular sections, a, between each one of which is a disk or flange, b, of largerl (No model.)

signaled. This form of tooth enables it to act readily and easily upon the arm that actuates the signaling apparatus. By making the cylinder in sections and casting them with the teeth, instead ot' a solid cylinder with teeth inserted in the same, we gain greater strength, and in case any ofthe teeth become broken or injured, so as to be unt for use, a new duplicate section can be readily substituted. A portion of each flange b is cut away, as shown at b', Fig. 2, in order to allow the arm L, hereinafter described, to be moved along the cylinder, so as to be adjusted to any desired section or set ot' teeth. The cylinder A is mounted on a shaft, C, which is rotated by means ot' a system of clock-work, or by any power applied thereto.

B represents an index-plate, arranged in front of the cylinder A', as shown, and is secured to the frame F. On the upper side ot' the indeX-plate are marked the severalconipass-points, below each ot' which are the tigures denoting the number of strokes to be struck, and corresponding with the number of teeth on the section ot' the cylinder to which they are opposite.- On the under side ot' the upper portion of the index-,plate B is.` a series of notches, each notch corresponding with a section ot' cylinder A.

I is a rock-shaft, made square in section, and

is supported in hangers or brackets K K, soV

as to admit of its being rotated or turned in its bearings.

Gr Gr' represent a pointer or indicator, ar` Aranged to slide laterally on the lowerbar, B', .of the index-plate B, upon which it is lsupported, as shown in Fig. 2. At the-rear ot' the upper end ot' the pointer Gr is a pin, c, which fits in the notches on the under side of the upper portion of the index-plate B, and serves to lock the index or pointer in place. The indicator or pointer G is held up by means of' a spring, M, attached to lever L, and is drawn down by pressing upon the thumbpiece H to unlock the pin c from the notches in indexplate B, a slot, f, in the part G of the pointer,

allowing of the free movementot' said spring M.

tends toward the cylinder A, its free end beo IOO ' between the flanges or extensions of disks b,

so as to be operated by the teeth on the cylinder as it rotates. It will be seen that as the lever Lis actuated by the teeth on the cylinder A it will impart to the rock-shaft I a partial rotation by the impact of each toothl on said cylinder. A pin. h, on the front end of lever L plays in a slot, g, in the pointer-frame G. O represents a bellor gong, arranged at the rear of the end of the cylinder A.

Upon the rock-shaft I, near its end, by the bell O, is iXed an arm, N, (shown enlarged in Fig. 3,) carrying the hammer N. P is a spring for holding the hammer-arm in place.

It will be seen that as the hammer-arm N is made fast to the rock-shaft I every partial rotation of the latter will move the arm N and cause the hammer N to strike the bell O, and as the rock-shaft I is partially rotated at each impact of the lever L with the teeth c on the rotating shaft A, it follows that at every passage of the lever L over the teeth c a blow will be struck on the bell or gong, thus indicating, by the numberofstrokes, thecourse the vessel is sailing.

In order to provide more effectually for indicating the course of a vessel at night, we connect the signaling apparatus with a flash light, so arranged that the several numbers indicating any particular course will be represented by a corresponding number of ashes of light, which is effected as follows:

Q represents a lantern, and is provided with a frame or casing, T, which is arranged to slide over the lantern and expose or conceal the light at will, the spring U serfing to retract the lantern within the casing` T after exposure. Any of the ordinary methods of producing a flash light may be employed. This lantern may be placed at the bow ot' a vessel, orin any other suitable part ofthe same, as required.

To the lower end of the casingT is attached a cord or rope, L, which is connected to the hammer-arm N, as shown in Fig. 3, so that every time the said arm is moved by the partial rotation of' the rock-shaft I to sound the bell the cord R will draw the casing T down and expose the light, the said casing returning to conceal the light as the arm Nresumes its normal position. l

Instead of being attached to the hammerarm N, a separate arm or lever may be secured to the rock-shaft I, for operating the cord R and casing T, if desired.

In the drawings, Fig. l, the pointer is set upon the index-plate to designate the course of the vessel as S. E., with the figures 3 l, indicating three blows on the bell, or three flashes of light, a pause, and one blow or flash. When the course ot' the vessel is to be changed the pin e is drawn down out of its notch by operating the thumb-piece H. The pointeris then slid along on the lower har, B, of the indexplate to such position as required, and the pin e enters the corresponding notch and locks the pointer.

The ianges b serve as guides to the leverL, to prevent any lateral movement of the same, as without such provision the signals would be liable to become changed, on account ofthe motion of the vessel or by accident in adjusting` the signals.

When the apparatus is used on a steamer a connection may be made with a steam-whistle, so as to signal by sounds from the whistle, in the place of, or in addition to, the strikingot' aA bell or the dashes of light.

What we cla-im as our invention, and desire to secure by Letters Patent, is-

1. In a signaling apparatus for vessels, the combination, with the sectional cylinder A, provided with the teeth c c, ot' a. stationary index-plate, B, extending the whole length of cylinder A, the laterally-adjustable pointer G G', the rock-shaft I, adjustable lever L, and the bell-striking device, substantially as and for the purpose set forth.

2. The laterally-adjustable lever L, in combination with the rock-shaft I, the hammerarm N, and the sectional toothed cylinder A, as and for the purpose specified.

3. In a signaling apparatus for vessels, the toothed cylinder A, made in sections separated froml each other b v [langes b, extending above the surface ofthe cylinder, so as toform guides for the lever actuated by the teeth ou the cylinder, substantially as set forth.

In testimony whereof we have signed' our names to this specification in the presence of two subscribing witnesses.
